The situation where one device has a stable mobile internet connection, while another desperately needs internet access, is familiar to many smartphone users. The question of how to share Wi-Fi from a Xiaomi phone is especially pressing, as the MIUI or HyperOS interface has its own unique setup features that differ from stock Android. Owners Xiaomi People often look for ways to turn their gadget into a full-fledged router to connect a friend's laptop, tablet, or smartphone.
The Hotspot feature allows you to broadcast 4G or 5G mobile data wirelessly, creating a local network. This solution is ideal for traveling, working in a cafe, or during temporary outages with your home ISP. However, to ensure a fast and secure connection, you need to properly configure the settings in the menu. MIUI.
In this article, we'll walk you through every setup step, from basic activation to advanced frequency band settings. You'll learn how to change your network name, set a strong password, and select the optimal security standard to protect your data from unauthorized connections.
Preparing your smartphone to work in router mode
Before activating the tethering mode, make sure that mobile data is enabled on your device. Without active Internet connections Sharing data is technically impossible, as the smartphone will have nothing to broadcast to the external network. Check your SIM card balance and your carrier's network coverage.
It's also worth paying attention to the battery level. Access point mode significantly increases power consumption, as the radio module operates in an enhanced mode of receiving and transmitting a signal. If the battery is low, it's best to connect your phone to charger or a power bank before starting a long session.
⚠️ Attention: When actively distributing Wi-Fi, the smartphone's body may become noticeably warm. This is a normal physical reaction under high load on the processor and radio module, but it is recommended to remove the protective case for better heat dissipation.
Make sure Airplane mode isn't enabled on your device and the necessary permissions are enabled. In some cases, especially after a system update, settings may reset, so an initial check of the basic settings will only take a minute and save time diagnosing the issue.

Basic hotspot setup in MIUI
The process of activating a function in shells Xiaomi quite logical, although the names of the points may differ slightly depending on the version MIUI or HyperOSThe standard settings path is generally the same for most models, from budget Redmi to flagship Mi.
To begin, open your device's main settings menu. Find the section that may be called "Connection and Sharing" or simply "Access Point." In some firmware versions, this option is located in a separate "More" submenu within the Wireless Networks section.
After entering the "Wi-Fi Hotspot" menu, you'll see a status switch. Toggle it on to start the server. The system will automatically generate a network name (SSID) and password, which will be displayed on the screen. This information will need to be entered on the connecting device.
- 📱 Open
Settingson the main screen. - 📡 Go to the section
Wi-Fi hotspot. - 🔘 Click the switch to activate the function.
- 🔐 Copy or remember the displayed password to connect.
It's important to note that the default security settings offered by the system are generally optimal for most use cases. The encryption protocol WPA2 PSK provides a sufficient level of protection for home use and work in public places.
Advanced Options: Frequency and Safety Standards
For users who want to get the maximum speed or ensure compatibility with older devices, the menu Xiaomi Advanced settings are available. They allow you to manually select the frequency range and encryption type, which is especially important in apartment buildings with high airborne noise.
One of the key options is the choice of radio frequency. By default, modern smartphones Xiaomi They can use the 5 GHz band, which provides high data transfer rates but has a shorter range and is less effective at penetrating walls. The 2.4 GHz band is slower but has a better range.
In the "Access Point Settings" section, you can change the network name (SSID) to whatever you prefer. This helps you easily identify your device in the list of available networks, especially if there are other phones nearby with similar default names.
⚠️ Attention: When choosing the 5 GHz band, make sure the receiving device (laptop or older phone) supports this standard. Otherwise, the device simply won't see the network.
The maximum number of connected devices is also configured here. Although the phone can technically handle up to 10 clients, actual performance will begin to degrade after 3-4 active users, so limit the number of connections for stability.
What is the difference between WPA2 and WPA3?
WPA3 is a newer security protocol that uses improved encryption algorithms and protects against brute-force attacks. However, if you have very old devices (manufactured before 2010), they may not connect to a network with WPA3 security, so in these cases, it's best to stick with WPA2.
Frequency Band Comparison: 2.4 GHz vs. 5 GHz
Choosing the right frequency is a balance between speed and coverage. Understanding the differences will help you fine-tune Internet connection The most effective solution for your current needs. Below is a table comparing the key characteristics of the two ranges.
| Characteristic | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Transfer speed | Up to 150-300 Mbps | Up to 400-800+ Mbps |
| Range | Large (up to 50 meters) | Medium (up to 20 meters) |
| Wall permeability | High | Low |
| Airtime congestion | High (a lot of interference) | Low (clear channel) |
If you are in the same room as the receiving device and you need to transfer a large amount of data or watch high-definition video, definitely choose 5 GHzThis will ensure minimal latency and high bitrate.
In situations where the handset is in one room and you're working in another, or there are too many neighboring networks causing interference, switching to 2.4 GHz may be a more stable solution. Adaptability settings are the key to a good signal.
Traffic limits and managing connected devices
shell MIUI Provides a convenient tool for monitoring mobile data usage, which is crucial if you don't have an unlimited plan. You can set a data limit, after which the hotspot will automatically turn off, preventing unexpected charges.
To set the limit, go to the access point menu and find "Traffic Limit" or "Data Limit." Here you can set the threshold in megabytes or gigabytes. The system will warn you when you're approaching the limit and stop sharing when it's reached.
This section also displays a list of all devices currently connected to your network. You can see their MAC addresses and the amount of traffic they're using. This allows you to quickly identify uninvited guests and, if necessary, block them or change their password.
- 📊 Set a daily or monthly traffic limit.
- 👁️ View a list of active clients in real time.
- 🚫 Block unknown devices with one click.
- 🔔 Set up notifications about new gadget connections.
Using these features turns your smartphone into a professional network management tool. You have complete control over who is consuming your data and how much. mobile Internet, which is especially relevant when traveling together or working in a coworking space.
⚠️ Attention: Tariff plans and service terms are subject to change. Before setting high data sharing limits, check with your carrier to ensure that excessive data sharing (P2P, torrents) does not violate network usage rules.
Troubleshooting connection issues
Despite the simplicity of setup, users sometimes encounter situations where the phone doesn't broadcast Wi-Fi or other devices don't see the network. Often, the problem stems from simple compatibility settings or temporary system glitches.
One common cause is the power saving mode being enabled. Aggressive battery optimization in Xiaomi may be killing the Wi-Fi connection in the background. If the network disappears a few minutes after turning on the screen, check the power saving settings and add the access point to the exceptions.
Another common issue is an IP address conflict or a network settings reset. If all else fails, try resetting your network settings. This will reset all Wi-Fi, Bluetooth, and mobile network settings to factory defaults, often fixing software errors.
It's also worth checking whether "Stealth mode" (hiding the SSID) is enabled in the access point settings. If this feature is enabled, the network won't appear in the list of available networks, and you'll only be able to connect to it by manually entering the exact network name.
Why does my phone's battery drain quickly when using Wi-Fi?
Access point mode forces the radio module to constantly receive and transmit signals at high frequencies, which is one of the most power-hungry processes in a smartphone. The processor is also burdened with network packet processing (NAT). To extend battery life, use the original charger or connect the phone to an external power source.
Is it possible to share Wi-Fi if the phone is connected to Wi-Fi?
This is possible on most modern Xiaomi models with Dual Band Concurrent Wi-Fi technology. The phone will receive Wi-Fi data and simultaneously broadcast it, acting as a repeater. However, this feature depends on the specific processor model and firmware version.
How to change the access point password?
Go to Settings → Wi-Fi Hotspot → Configure Hotspot. In the "Password" field, enter a new password (at least 8 characters) and save the changes. All connected devices will need to reconnect with the new password.
Why does the laptop see the network but not connect?
Most often, the issue lies with the encryption type or frequency range. Try changing security from WPA3 to WPA2/WPA3 Mixed or switching the access point frequency range from 5 GHz to 2.4 GHz in your smartphone settings.
